0x40 REQ_WRITE_RADIO_PARAM Request to update the radio parameters
0x41 RES_WRITE_RADIO_PARAM
Response from the radio board to the radio parameters
update
0x50 REQ_READ_RADIO_PARAM Request to read the radio parameters.
0x51 RES_READ_RADIO_PARAM Response from the radio board to a parameters reading.
Remark : In the command byte coding, the Response frame type are taking the Request command
byte value with the LSB bit set to 1.
Data field formats to read or to update the radio parameters is the following :
